1、湖南大学毕业设计第121页地基基础及地下结构综合设计摘要岩土工程是一门专业领域广、理论与实践紧密结合的学科，主要包括边坡与基坑支护、隧道及地下建筑工程、地基处理、基础工程等内容，其以土力学和岩体力学为基本课程，基础工程、地基处理、边坡与基坑支护、地下结构设计原理与方法等为专业课程。最近几十年，随着国内外高层建筑、高速公路、隧道等的蓬勃发展，岩土工程获得了丰富的实践经验和理论成果。本地基基础及地下结构综合设计共包含四部分，分别为住宅小区基坑支护设计、某商住楼基础设计、某二级公路软土路堤路基加固设计和姜源岭隧道设计，其中
2、基坑支护采用土钉墙支护、高层建筑采用箱形基础、软土路基分别采用堆载排水固结法和水泥土搅拌桩复合地基法设计并选择合理方案，隧道主要针对深埋埋V级围岩采用喷锚和钢架复合支护。由于时间有限，各设计中主要以结构设计为主，施工组织概预算与质量监测等内容为辅。关键词：土钉墙，箱形基础，堆载预压法，V级围岩复合支护湖南大学毕业设计第121页ThesyntheticdesignofGroundfoundationandUndergroundstructureAbstractGeotechnicalengineeringisabroa
